Bidders should engage a design consultant with experience in providing consultancy services for developing solar power projects for a minimum of 30 MW or above capacity in a single location in the last seven years.

For the quoted capacity of 100 MW, the average annual turnover of the bidders should be at least ₹1.65 billion (~$20.67 million) in the last three consecutive financial years.

In March this year, NLC India invited bids to set up 100 MW of ISTS-connected solar power projects on a pan-India basis.

Earlier, NLC India had invited bids for the enlistment of domestic EPC vendors to construct ground-mounted solar projects being developed by NLC India and the Coal Lignite Urja Vikas Private Limited.
